The Team Behind Santa Clara's Custom Builds
38Carmodz is a specialist modification shop led by Mario, built on decades of hands-on experience with exotic and performance vehicles.
Our story
Built by Enthusiasts, Trusted by Owners
A shop culture obsessed with fitment and finish
What began as after-hours work on friends' project cars grew into a full facility on Martin Avenue serving Santa Clara, San Jose, Sunnyvale, Cupertino and the wider Silicon Valley. Our reputation was built by word of mouth from owners who noticed the difference in panel gaps, wrap edges and suspension behaviour.
Today the shop handles everything from a single lip install to multi-month widebody builds with air management, custom interiors and full protection packages. The approach never changes: measure, plan, execute, verify.
Our guarantee
We stand behind our high-end automotive modifications with a 100% satisfaction guarantee, ensuring your custom build meets the absolute highest standards of quality, aesthetics, and performance.
Our mission
Elevate Every Build to a Standard Worth Showing
Protection, perfection and personalization for high-end vehicles
To protect, perfect and personalize luxury and performance vehicles through obsessive craftsmanship, honest communication and a controlled shop environment where no detail is too small.
Core values
What Guides Every Decision at 38Carmodz
The non-negotiables behind every build we accept
Owner-First Communication
You speak directly with the technician and owner overseeing your build — no gatekeepers, no surprises.
Uncompromising Integrity
Honest quotes, documented scope and a written guarantee on every project we touch.
Continuous Precision
Measure twice, install once and verify on our own alignment and inspection setup every single time.
How we work
Standards We Refuse to Compromise
Three principles that govern every build
Precision over speed
We would rather hold a car an extra week than release a build that is 95% right.
Owner accountability
Mario personally inspects and signs off on every vehicle before delivery.
Specialist focus
High-end sports and luxury platforms only — that focus is what protects your investment.
